The service provides access to a number of datasets containing recorded levels of environmental variables measured and tracked by the U.S. Environmental Protection Agency. A number of datasets document various monitoring programs over time tracking pollutants and environmental conditions affecting air quality, water quality, and land-borne contaminants. EPA staff and contractors can access both current and historical data via the service, built as an instance of ESRI Geoportal Server.
API methods support listing of available datasets and selection of desired data based on location and conditions of interest to a researcher. Methods also support retrieval of desired datasets in formats suitable for further analysis.
The following is a list of historical changes that were made to this asset. Typically, once an API is published on ProgrammableWeb.com, the data we keep about that asset gets updated over the course of its life. For example, the endpoint or home page of the documentation might change. As a means of enforcing the integrity of our data, every time a non-trivial change is made to the data we keep about an asset, we require the entry of some changelog text before that change can be saved. This way, we have a great audit trail of all activity surrounding the asset. For each asset, the changelogs begins with the moment an asset is approved for publication on ProgrammableWeb. If you spot an error in our data and believe that a record needs to be updated in some way, the ProgrammableWeb team would very much like to hear from you at firstname.lastname@example.org
So far, we don't have a record of any changes to this API
